TIRE-PROTECTOR ANCHOR Specification of Application filed. June 2,

Letters Patent.

Patented Nov. 2}, 1909.

Serial No. 499,775.

. previous patent- Xo. 898,714, dated Scptemher 15, 1908. is set forth in said previous patent, the protector or covering for the tire is secured in place by 'a pair of fiat rings along the opposite margins thereof. said rings being connected across the telly by tension devices. in the present invention similar tension rings are employed in connection with the protector or covering for the tire, and a special form of tension device is used in connection therewith.

For a full understanding of the invention, reference is to be had to the following detail description and th awompanying drawings, Ill which:

'Figure l is a perspective View of a wheel equipped with tho improvemei'it; Fig. 2 is a detail perspective of one of the ratchet connections; Fig. 1 is a longitudinal seetion'ot one end of the device of Fig. 9, Fig. at is a transverse section of the same, and Fig. 5 is a detail ol a hook.

'lhroughoul the "following description an 1 on the several figures of the drawings, simi lar parts are referred to by like reference characters.

Referring to the drawings, the wheel equipped with a tire 11. is shown as being provided with an armor or tire protector 12, of any suitable material such as heavy leather. and provided with special protecting devices 12-3. The lateral edges of the protector body are slitted so as to enable the protector to snugly embrace the tire inclosed thereby. Said lateral portions of the protector thus form a series of tongues or flaps 14 on each side of the tire. To each of said flaps is connected a metallic plate 15 adapted to receive the ring 16 either directly or by means of a hook 17 connected to the plate.

The ring 16 maybe made in one piece if desired, as in the previous patent above referred to, but preferably it is made in two segments 16 in order that the points of adjustment may be better distributed. The

ends of the ring segments 16 are provided Y with a plurality of transverse notches or holes 16, and the adjacent ends of the two segments are adapted to be interlocked in a ratchet connection of peculiar form. Said ratchet connect-ion comprises a flattened tubular socket 18 rigidly and permanently connected to a strong metallic plate 19, preferably permanently connected to several of the flaps 1 10f the protector. The plate 19 is provided preferably at its ends with a pair of hooks 19 which embrace the said tubular socket 18 and to which the socket is permanently connected, as by rivets 19.

the full length between the hooks 9. The

tubular member 18 and a pawl 20 carried by the tubular member automatically engages into the holes 10' of 7 said segments. The pawl 20 is provided at each end with a hook "20 extending into uthe tubular. member 18 ward the center or middle portion of said member 18. The main portion of the pawl 20, between the hooks 20, is flat and serves as a spring, as hereinafter fully set forth. Surrounding the tubular member and the pawl 20 are rings 21 which are slidable above between the member 18 and plate 19.

-In assembling the devices, the ring segments 16 are placed in position in the hooks 17, the protector having been slipped around the tire in the usual manner, and the ends of the ring segments are then introduced into the ends of the members 18; the hooks of the pawls will then snap into the first holes 16 thereof. A special tool, not shown, in the nature of a spanner is then applied to certain 01 the holes 10 on the outside of the members 18 whereby the ends are caused to approach each other within the member 18, step by step, the hooks 20 of the pawls snapping into the holes 16 as they are reached. The rings 21 may be placed midway of the pawl during this operation, or they may both be caused to occupy a place at the ends of the pawl so as to enable a longer portion of the spring of the pawl to be utilized. After the adjustment has been completed, the rings 21 will be moved to the ends of the'space between the member 18 and plate 19 and secured at such plates by from the outside and thence directed totherealong by virtue of the space referred to respective ends of the pawl at the opposite.

Between the main body of the plate 1.5) and the socket member 18 IS a narrow space extending substantially ends ofthe ring segments 16 are adapted to be introduced into the opposite ends of the any suitable-means. As indicated in the drawings, the said rings 21 are held in place I normally by means of dogs 22 connected to engagement with the rings when it is de' sired to change the adjustn'ient of the tension device. It will be noted that the hooks of the pawls are inclined on their inner faces and the holes 10 ot' the ring segl'nents are elongated so as to admit said hooks: The peculiar form of hooks serves to draw the ring segments snugly against the inner face of the members 18, thus preventing accidental displacement.

The ratchet connecting mechanism above describedis neat in appearance, taking up comparatively little space, strong and reliended pawl carried by said tubular member,

able in use, and is such that it is practically impossible for the tension members to become loose after once adpisted, except by the application of the tool when it is do j sired to change the adjustment. It is not infrequent for tension devices for pneumatic tires to become loose when the tire becomes deflated for any reason, but with this device the protector and tension devices always remain in proper position.

The plates 15 are attached permanently to the protector and the hooks 17 are closed forming loops into and through which the segments 16 are slipped-endwisc. Thus it will be seen that it is impossible for the devices to become displaced after once being assembled, even though the tire should hecome deflated.

Having thus described this invention, whatis claimed asnew is 1. A pneumatic tire protector comprising carried by some of said flaps, and a double ended pawl carried by said tubular'member and extending into the interior thereof for cooperation with the ends ot'the tension ring introduced therein.

2. The herein described tension device for a pneumatic tire protector comprising a flat metallic ring the ad acent ends ot which are perforated, a flattened tubular member to receive said ends, said tubular member having a hole in its side near each end, a double the ends of which project into said holes for cooperation with said ring ends, and means surroimding said pawl and tubular member and slidable therealong for maintaining the pawl in normal position.

3. In con'ibination, a protector having a se'- ries of marginal flaps, a plurality of plates having integral closed hooks connected to said flaps, tension ring segments slipped endwise into said hooks, and ratchet mechanism including a double hooked pawl cooperating with the adjacent ends of the said ring segments. I

In testimony whereof I afiix my signature in presence of two witnesses.
